Problems solved by technology

[0010] However, the above method has the following problems. As long as the RFID tag is within the radio frequency transceiver range of the reader, the reader can obtain the ID, and the illegal reader can read the data in the RFID tag according to the obtained ID, resulting in data leakage. In addition, since the RN16 sent by the RFID tag to the reader is sent in plain text, the illegal reader can also obtain the RN16, write data to the RFID tag according to the RN16 and ID, and destroy the security of the data

Embodiment Construction

[0030] The basic idea of ​​the present invention is: the reader-writer counts the RFID tags, sends an ID reading command to the RFID tag, the RFID tag encrypts the ID and sends it to the reader-writer, and the reader-writer obtains the ID.

[0031] The present invention will be described in detail below through specific embodiments and accompanying drawings.

[0032] A method for RFID tag identification, such as figure 2 As shown, the specific steps are as follows:

[0033] Step 201, the reader checks the RFID tags, and sends a read ID command to the RFID tags;

[0034] The reader sends a tag inventory command to the RFID tag, and the sending is broadcasted by the reader to all RFID tags within its radio frequency range; after the RFID tag receives the tag inventory command, its internal random number generator generates RN16, and at the same time , encode the RN16, and send it to the reader according to the anti-collision algorithm. The RN16 generated by each RFID tag is d...

Abstract

The invention discloses an RFID (radio frequency identification) tag identification method. The method comprises the following steps: a reader checking an RFID tag; the RFID tag generating a random number and transmitting the random number to the reader; the reader transmitting a unique identification (ID) code reading command including the random number to the RFID tag; and the RFID tag encrypting ID according to the random number and a preset encryption algorithm, and transmitting the encrypted ID to the reader. The invention also discloses an RFID tag identification system. The method and the system provided by the invention can enhance ID identification security and ensure safe transmission of RFID tag data, thereby facilitating development of RFID technique.

Description

technical field [0001] The invention relates to the field of radio frequency identification (RFID), in particular to a method and system for identifying an RFID tag. Background technique [0002] With the wide application of RFID technology, RFID tags are gradually used in people's daily life. RFID tags are composed of coupling elements and chips, attached to objects, and identify objects by storing object data. The data includes a unique identification code ( ID), the feature information of the object, etc. The feature information of the object is information that can characterize the characteristics of the object, such as the balance information of the bus card, etc. RFID tags are widely used in various fields such as product anti-counterfeiting, logistics, and product monitoring. [0003] Radio frequency is a kind of wireless communication technology. All devices within the range of radio frequency transmission and reception can receive and emit electromagnetic waves. In ...
